The present invention relates to a device for creating, maintaining and removal of vacuum, for example, in the tank, designed for the collection and transport of waste in the vacuum toilet. This invention also relates to systems that include a vacuum device made in accordance with the present invention.Known vacuum ejectors operating on the Venturi principle used to create an auxiliary pressure, for example, in the United with him in the tank. Such ejectors are able to create vacuum up to 90%.When the ejector such a vacuum device connected to the system, including the reservoir and the channels of compressed air to create pressure and vacuum, the installation and connection of such systems typically requires a large amount of additional elements. In such systems cannot be used conventional ejector, unless there is a significant number of additional devices, especially in the toilets with vacuum system.To maintain the vacuum generated in the device, which is connected with the reservoir, known as vacuum devices include about the ejector.The use of the check valve creates a number of difficulties. First, it complicates the integration of all the necessary functions in the vacuum device, as in this case, when you need to empty the tank of compressed air must be supplied through a separate channel, and, secondly, it is impossible to create a self-cleaning device, since the check valve does not allow air to pass from the ejector into the tank. Known systems are also bulky and heavy.The aim of the present invention, therefore, is to eliminate the above disadvantages by creating a vacuum device, similar to the above, in which United all necessary operational functions, which have the ability to cleanse itself, it would be lighter in weight than known designs, and easier to install than the above known device.Another objective of the present invention is to provide a toilet with a vacuum system including such a vacuum device.Basically the present invention is based on the idea that consists in the fact that these goals can be achieved using a vacuum device, in which a check valve instead of the traditional version of the installation and with the present invention, the vacuum device comprises a first valve, which can be connected with a compressed air source, a second valve which can be connected to a source of compressed air, the ejector comprising an input nozzle outlet and the vacuum passage, and the ejector is connected to the first valve through the inlet nozzle, and the first connection node through the vacuum passage, and also contains a piston control valve having first and second inputs and an output, with the piston control valve connected to the outlet pipe of the ejector through the first inlet, the second valve via the second input and the second connection node, installed on the vacuum device through the output; the device further includes a check valve installed between the output piston of the control valve and the connection node, and a bypass channel connecting the second valve and the second inlet piston of the control valve with the inlet of the ejector.In this configuration, it becomes possible to create a compact, self-cleaning vacuum device, which includes an ejector located in the center of the device. Inlet of the ejector is directed essentially at right angles to the input and output pipe.Preferably, the valve E, the preferred embodiment of the vacuum device includes a pressure gauge and safety valve, which are connected with the first connection node, mounted on the device.The device with this structure can be easily made from polyformaldehyde by injection molding.In accordance with a preferred embodiment of the invention in the composition of the first connection node that is installed on the device, includes a filter designed to prevent the ingress of harmful particles.The present invention also relates to toilet with vacuum system including the above-mentioned vacuum device.Hereinafter the invention will be described in more detail with reference to the example of its implementation, and with reference to the accompanying drawings, on which:
Fig. 1 depicts a perspective view of a vacuum device in accordance with the present invention;
Fig. 2 is a diagram showing the main part of the construction of the vacuum device shown in Fig. 1;
Fig. 3 is a view in section of a vacuum device shown in Fig. 1;
Fig. 4 is a schematic depiction of the construction of the toilet, which includes a vacuum device that is the subject of the present invention.Below, preferred is a device.Device 2, which is shown in Fig. 1 and schematically depicted in Fig. 2, includes three valve 4, 6, 8 with electromagnetic control, each of which can be connected with a source of compressed air through the corresponding input 11, 12, 13. Although the illustrated vacuum device includes three mentioned inlet for compressed air, it should be understood that the three valve 4, 6, 8 with electromagnetic control can alternately be connected with one common inlet of compressed air to the vacuum device.The first solenoid valve 4 controls the flow of compressed air to the input nozzle 10a of the ejector 10. The main purpose of the electromagnetic valve 6 is to control the passage of compressed air through the connection node U1 to porshneva the control valve 16. The third electromagnetic valve 8 controls additional functions outside of the device.The ejector 10 in more detail is shown in Fig. 3. The function of the ejector 10 is to create a vacuum in the space inside the ejector, when the air flows from the inlet nozzle 10a to the outlet nozzle 10b, resulting in a depression in the devices connected with the above-mentioned space through the HAC is owned by valve 4, and the vacuum passage 10c is connected to the first connection node U1, installed on the vacuum device. The filter device is preferably inside the first connection node U1 or beside him.The output nozzle of the ejector 10b is connected to the first input 16a of the piston control valve 16. In the piston control valve output 16c is connected with the second connection node U2 is installed on the device, through the check valve 17, which allows air to pass from the output 16c of the piston control valve. The air channel may be connected to the connection node U2 to get a fully closed system.The piston valve 16 is connected with the second solenoid valve 6 through the second input 16b. In contrast to the known vacuum devices this second input is also connected with the following input 10d ejector, which is usually located at right angle to the input nozzle 10a of the ejector and to the outlet nozzle 10b.The vacuum device 2 also includes a third solenoid valve 8, which is used to apply pressure on other elements of the system via the third connection node U3 on the vacuum device. This third electromagnetic valve 8 I the TWT 2 also includes a pressure sensor 18, which is connected to the connection node U1. When in the tank, which is connected to a vacuum device through the connection node U1, vacuum is created, the sensor sends a signal to the control unit (not shown).The inventive device includes a relief valve 19, which is also connected to the connection node U1.In the present invention, the device 2 is made preferably by way of injection molding of polyformaldehyde.The operation of the device which is the subject of the present invention, will now be described with reference to a typical operating cycle used in the toilets with vacuum system.This system is illustrated in Fig. 4 and includes a latrine or toilet 20, which may be a conventional vacuum toilet and which is connected through an inlet valve 22 with the tank 30 with the normal pressure for the intermediate storage of the material entering the tank from the toilet 20. In the case of the preferred variant of the invention, the reservoir has a capacity of about 5 liters, although in normal operation it is not filled more than 2 DL.The system also includes a receptacle 26 for collecting Oktavia using management tools. The container 28 with water is connected to the toilet 20.The system also includes a device 2, which is the subject of the present invention, which is driven by means of compressed air supplied from a compressed air source. The first connection node U1 vacuum device is connected with a reservoir of high pressure 30 through the filter 38, the second connection node U2 vacuum device connected to the channel 34 through the vent channel 36, and the third connection node U3 vacuum connection connected to the container 28 with water.In the tank 30 initially has no vacuum. When the first solenoid valve 4 is actuated, for example, by means of an electrical pulse with a DC voltage of the order 24B from the power source (not shown), compressed air flows through the valve from a source 32 of compressed air. The air passes through the ejector 10 from the input nozzle 10a of smaller diameter and enters the outlet 10b of larger diameter, thereby creating a vacuum or negative pressure in the ejector 10, and the reservoir 30. The filter 38 is present between the device 2 and the reservoir 30, prevents retraction of the large particles from the tank to the ejector 10. the EN 16, then passes through the check valve 17, and then exits through the second connection node U2 vacuum device 2. The air continues to flow through the air channel 36 and through the output channel 34, where it performs the function of cleaning. The check valve 17 located between the output 16c of the piston control valve 16 and the connection node U2 vacuum device, provides the air passage in this direction.At this stage of the business cycle the valves 22 and 24 are closed.When the tank 30 creates a vacuum, with a pressure sensor signal to the vacuum device 2. In this case the electromagnetic valve 4 is closed and the toilet is ready for use. At this stage, the check valve 17 prevents the ingress of air into the reservoir 30 of the duct 36 through the piston control valve 16 and the ejector 10. If for any reason the tank 30 reaches the air and the vacuum is broken, the process returns to the initial stage when triggered, the first electromagnetic valve 4.Vacuum toilets can be prepared thus to signal the lowering of the water in the toilet or vacuum creation may begin in response to a signal lowering of water. Signal SDA switch, connected to the lid of the toilet. When a signal is received from the lowering of the water and in the tank 30 has a vacuum inlet valve 22 is opened and the negative pressure existing in the reservoir 30 provides suction the contents of the toilet tank with water from the container 28 to the water, which at this stage is pumped through the third solenoid valve 8.After complete absorption of the contents of the toilet tank 30, the inlet valve 22 is closed and the outlet valve 24 opens. At this stage, the second solenoid valve 6 opens and allows passage of compressed air to the ejector at a right angle to the inlet nozzle and the outlet nozzle, and at the same time the piston of the piston valve 16 is shifted due to the fact that it has a large surface area facing the entrance 16b than the surface area facing the entrance 16a. The piston thus blocks the passage of air through the second connection node U2 vacuum device, except for a very small period of time immediately after activation of the second solenoid valve 6, and this length of time can be neglected. Then all the air will pass through the ejector and into rise time when the reservoir 30 is emptied into the collector container 26.Then the second solenoid valve 6 and outlet valve 24 is closed, preferably with a time control, and the procedure can be repeated.Although vacuum device which is the subject of the present invention, described above with reference to preferred implementation, it is necessary to understand that the illustrated embodiment of the invention may be modified in several respects within the scope of the claims of the present invention. For example, the filter 38 may be part of a vacuum device to make the design compact.Moreover, although the ejector presented in the preferred embodiment of the invention, includes one inlet nozzle and one outlet, you need to understand that the ejector may alternatively include multiple inlet nozzles and outlet nozzles. 1.
